Definitions
- the present invention relates to a woven substrate which is formed into a three dimensional article by thermoforming or other means suitable for purpose.
- Fiber reinforced composite structures enjoy the benefit of being lightweight while providing mechanical 'advantages such as • strength.
- molded plastic, wood or metal structures are preferred due to the cost involved, since they are relatively easy to fabricate.
- articles, such as package or storing crates are prone to damage due to the rough handling involved or are limited in their stacking ability due to weight and strength considerations.
- fiber reinforced composite structures would be more desirable, the expense involved in making a somewhat complex three dimensional (3D) structure is a consideration.
- composite structures start off typically with a woven flat substrate of fibers.
- the substrate then has -to be shaped into the form of the article which is then coated with a resin and thermoforme'd or cured in the desired shape.
- This may be readily done for relatively flat or smooth surfaces.
- angled surfaces such as at the junction of the sides,, corners and bottoms of a box or crate, cutting or darting is required.
- This is somewhat labor intensive and adds to the cost of manufacture.
- woven 3D structures may be woven by specialized machines, the expense involved is considerable and rarely is it desirable to have a weaving machine dedicated to creating a simple structure. Accordingly, while woven fiber reinforced articles are desirable in many applications to replace comparable plastic, wood or metal structures, there exists a need to reduce the cost involved in the method of their manufacture. By doing so it may also allow for their relative mass production and wide spread application.
- a yet further object of the invention is to avoid the need for special weaving equipment to create 3D structures.
- a still further object is to provide for a method of creating a woven reinforcing fabric which may be readily adapted to create a wide variety of different 3D structures.
- the present invention is directed toward providing a specially designed fabric suitable as the reinforcement for a 3D composite structure.
- the fiber reinforcement is one that may be woven on conventional weaving machinery. It starts off as a woven 2D structure that is then formed into a 3D structure, particularly one having deep draws.
- the reinforcing fabric is woven in a manner that, in portions of the weave, the warp and weft or fill fibers are laid on each other and do not interlock. In this portion the fibers can move independently and slide past one another when the fabric is .
- portion is a rectangular or square shape, it can be collapsed in such a manner that both the warp and weft fibers fold upon themselves and each other to align in an unidirectional manner which creates a corner which acts as a compression column in the final structure.
- Figure 1 illustrates the construction of a flat 2D woven fabric incorporating the teachings of the present invention.
- Figure 2A-2D illustrates the sequence of folding or drawing down the fabric to produce deep draws .
- Figure 3 illustrates a 2D fabric ⁇ ⁇ having multiple areas where warp and weft fibers are not interwoven to create a complex structure upon folding or drawing down.
- Figure 4 is a perspective view of a 3D structure formed from the fabric shown in Figure 3.
- FIG. 1 there is shown a flat 2D woven reinforcement fabric 10 which illustrates the present invention.
- the fabric 10 may be woven using any conventional textile pattern such as plain, satin, twill, etc. or any other pattern suitable for this purpose.
- the fiber used can be any fiber that can be woven, synthetic or natural, including for example fibers made from glass, Kevlar®, carbon, nylon, rayon, polyester, cotton, etc. and may be woven on conventional weaving equipment.
- the warp fibers are shown in direction A with the weft fibers in direction B.
- the fabric 10 has been divided into regions 12 through 28 divided along fold lines 30-36.
- regions 12-18 and 22-28 the fibers are woven in a" conventional fashion with the warp fibers intersecting with the weft fibers.
- these fibers do not interlock, in other words the weft fibers, float beneath the warp fibers.
- the fibers can therefore move independent of one another.
- the fabric 10 can then be formed into the desired shape. If it is to act as a reinforcing structure, the fabric -can be impregnated with the desired material or resin and then formed or thermoformed into shape. Alternatively, co-mingled tows consisting of a structural fiber and a thermoplastic resin could be woven to produce a preform which is then thermoformed.
- FIG. 2A shown in Figure 2A is the flat 2D woven fabric 10.
- the fabric 10 is then folded along fold lines 30 and 32 which are parallel to the warp fibers, as shown in Figure 2B.
- the fabric 10 is then folded along fold lines 32 and 36 which are parallel to the weft fibers and perpendicular to the warp fibers, as shown in Figure 2C.
- the warp and weft fiber in region 20 are not interlocked, they slide past one another and ultimately accumulate in corner 38 as shown in Figure 2D.
- the fibers in corner 38 are now unidirectional and can act as a compression column and increase the strength of the structure being formed.
- the foregoing can be done automatically by thermoforming equipment having the desired shaped mold, or by other means suitable for this purpose; then the structure heat set or cured.
- the foregoing advantageously avoids the need for cutting or darting, thereby reducing the amount of labor required and the ultimate cost of the article.
- the present invention allows for the increased automation of the fabrication and therefore broadens the applications for which reinforced structures may be used.
- Fabric 110 illustrates a plurality of regions 120 wherein in the woven structure, the warp fibers merely lay on the weft fibers. With such a fabric 110, it may be folded and shaped into a complex reinforced structure 130 as shown in Figure 4. Of course other shapes can be created by varying the size and location of the regions where the warp and weft fibers do not interlock.
